ALSA: hda: Add STAC92HD83XXX_PWR_REF quirk
Some revisions of the 92hd8xxx codec's not supporting port power downs in which the using of it causes capture and also randomly playback streams to not function at all. Thus by disabling it by default and adding a option to enable it manually will fix all issue on current and future revisions.
